Sweatpants and joggers are the same garment on this page. Jogger usually means a cuffed, tapered leg. Sweatpants is the broader term that also covers a straight or open hem. We make both, and the decisions further down are what separate them.
This is cut and sew, not print on demand. We hold no stock garments, so nothing is pulled off a shelf and decorated. Patterns are developed for your leg shape and rise, graded across your size range, then cut, stitched and finished by hand.
You do not need a tech pack to start. A sketch, a moodboard, a reference photo or a pair you already own is enough. We handle the pattern and fit development from there. If you are building a bottom to sit under a hoodie, read the section on matching below. It is the part most founders underestimate.
Sweatpants production at a glance
Everything below is standing policy, not an estimate. Where a figure is a range, the range is real and depends on your spec.
Send a sketch, a moodboard or a pair you already own. All three work.
Two decisions do most of the work: how heavy the fabric is, and how the inside face is finished. On a bottom, the first one matters more than it does on a top.
GSM is grams per square metre, the standard measure of how heavy a knitted fabric is. A hoodie hangs from the shoulders and forgives a lot. A leg hangs from the hip with a knee in the middle of it, so weight is what decides whether your pattern reads the way you drew it.
| Weight | How it hangs on a leg | Typically used for |
|---|---|---|
| 240-280 GSM | Light to midweight and fluid. Follows the leg and moves with it, so a taper reads as a taper rather than a tube. | Warmer-month drops, lounge bottoms, lighter tracksuit bottoms. |
| 300-350 GSM | The standard midweight jogger. Enough body to hold a cuff without collapsing, light enough to sit comfortably behind the knee. | Core range staples, a first drop, everyday brand pieces. |
| 380-420 GSM | Heavyweight. Hangs as a column rather than draping, so a straight or wide leg keeps the line it was drawn with. | Premium streetwear, wide and straight legs, garment-dyed and washed pieces. |
| 450 GSM and up | Very heavy, closer to outerwear. Holds its own shape entirely, stacks hard over a trainer and takes a while to break in. | Statement pieces and limited runs. |
The failure modes are predictable. Light cloth on a wide-leg pattern collapses and clings instead of hanging. Heavy cloth above a rib cuff blouses more than most founders expect, and it bunches behind the knee when you sit down. Heavier fabric also uses more yarn and adds weight to your shipment, so it changes your quote. If you are unsure, send us a pair whose weight you like and we will match it.
Loopback and brushed fleece start life as the same knit. Fleece is terry that has been brushed; loopback is terry left exactly as it came off the machine. On a bottom, that one finishing step decides how the garment ages, because legs rub against each other in a way that a torso never does.
| Fabric | What it is | How it wears on a bottom |
|---|---|---|
| French terry (loopback) | Knitted with loops on the inside face, left unbrushed. | Breathable, dries quickly and keeps a crisp outer face. It handles the friction at the inner thigh better than a brushed fabric, and it is the usual choice at heavier weights. Less instantly soft. |
| Brushed-back fleece | The same loop structure, brushed out into a soft nap. | Warm, soft against the skin and fuller in the hand. The familiar high street jogger feel. The nap flattens and pills first where the legs meet, which is exactly where nobody wants it. |
| Cotton-rich or blended | 100% cotton against a cotton-polyester blend, sometimes with a little elastane. | Cotton takes garment dye and acid wash best. Blends resist shrinkage and hold printed colour, which matters on a garment that gets washed often. A small amount of elastane helps a tapered leg recover at the knee. Sublimation needs a polyester-rich fabric to work at all. |
Still deciding? Ask for both finishes on your sample. Sampling comes before bulk on every order, so it is the right point to settle it.
Fabric is dyed in batches. Two rolls of the same cloth, dyed to the same recipe on different days, can come off the line fractionally apart in tone. Nobody notices that on a single garment. Put the joggers next to the hoodie in daylight and half a shade is the first thing anyone sees.
It gets harder when the two pieces are not the same cloth. A brushed-back hoodie and a loopback jogger take dye differently on an identical recipe, because the surface, the pile and the fibre content all change how light comes back off the fabric. A garment-dyed or washed finish adds another variable on top of that.
Making both together is the easier problem. Your colour is fixed to a Pantone reference at the start rather than described in words, so "washed black" or "off-white" means one specific thing to everyone handling the order. Fabric is custom-dyed or sourced to that reference. Both fabrics are then matched to the same reference and checked against each other before anything is cut. Fabric inspection is the first of our four quality control stages, and it happens before the cutting table rather than after it.
If the hoodie already exists, send us the actual garment rather than a photo. Screens render colour differently on every device, and a photograph of a black hoodie tells us almost nothing. With the physical piece in hand we can match to it and to a Pantone reference at the same time. Be straight with yourself about one thing though: a hoodie from an earlier run was dyed in a batch that no longer exists, so we match as closely as the fabric allows and you confirm the result on your sample before bulk begins. Lay the joggers on the hoodie in daylight, not under a lamp. That is the check we ask every client to make.
If you are building the top half too, see hoodie manufacturing. If you want the whole set quoted as one job, tracksuit manufacturing is the page for that.
A leg is a tube, and it is a tube that bends in the middle. Where the artwork sits changes both how it reads and how the garment has to be built, which is why placement is settled before cutting rather than added at the end.
| Placement | How it reads | Worth knowing |
|---|---|---|
| Front thigh | The default. Sits below the hip and above the knee, visible standing and walking. | Too high and the pocket opening gets in the way; too low and it folds out of sight when the wearer sits down. |
| Hip and pocket | A small mark beside or above the pocket opening. Restrained, and premium at small scale. | Embroidery here has to clear the pocket bag sitting behind the panel. |
| Down the side seam | A taped stripe, piping or a repeated wordmark running the length of the leg. | The hardest to execute well. It runs alongside a seam for the full length, so a wander of a millimetre shows the whole way down. Checked at the in-process stage. |
| Seat and back yoke | Sits under the waistband at the back. Reads on a rear-view shot. | Keep it clear of the waistband seam, or the elastic distorts it once the garment is worn. |
| Above the hem | A mark just above the cuff or the hem, seen when the leg stacks. | On a cuffed leg the artwork has to clear the gather. Sit it on the gather and it warps as the rib pulls in. |
| Waistband | Branded elastic, an embroidered mark, or the cord tips. | The detail a customer sees every time they put them on. Specified with the trims rather than with the print. |
Two constraints run underneath all of it. The first is that a finished leg is a closed tube, so flat processes such as screen print and DTF have to be planned around the sewing order rather than applied at the end. The second is grading. A graphic measured down from the waistband and the same graphic measured up from the hem land in different places once the pattern is graded across your size range, so we fix which reference point the placement is taken from and you see the result on your sample.
The methods are the same ones we run across every garment: embroidery, screen print, DTF, sublimation on polyester-rich fabric, chenille patches, and acid wash as a finish rather than a graphic. Custom labels, woven tags and custom trims sit alongside any of them.
Custom tracksuit made for King Promise
This tracksuit was made for King Promise, top and bottoms cut and sewn to the same spec. We also manufacture for Che Lingo, Blanco and Grace Ajilore, and our work has appeared in NME, Teen Vogue, the Crunchyroll Anime Awards and Retail Jeweller.
Yours starts the same way: your leg shape, your rise, your fabric weight, your waistband, your labels. Send what you have and we will quote it.
Send whatever exists: a sketch, a moodboard, a reference photo, or a pair you already own that fits the way you want yours to fit. We will ask about weight, leg shape, rise, hem and waistband, then send a tailored quote. If your design is not finished, our team provides full design support and handles the technical development.
Once the quote is agreed we develop the pattern: rise, seat, thigh width, taper, inseam length, leg opening, waistband depth and the cuff. It is then graded across your full size range, so an XL is the same jogger as a small rather than a longer, wider guess.
We hold no stock, so fabric is sourced or produced for your order at the weight and composition you chose. Pantone colour matching and custom-dyed fabrics are available, and where the bottoms have to sit alongside a top, both fabrics are matched to the same reference. Elastic, cords, eyelets, tips, custom labels and woven tags are specified now, and decoration placement is planned in before anything is cut.
You get a pair in your hands before anything goes to bulk. Wear them, sit down in them, wash them, and put them on someone at the other end of your size range. A free sample of each design is included with every committed bulk order; a standalone sample without a bulk commitment is charged. One sample revision round is free, further revisions are chargeable, and changes to your quote are always free.
Your approved sample becomes the reference for every piece in the run. Sweatpants are cut, stitched and finished by hand at our own dedicated facility, with your labels, tags and trims applied to spec.
Every order passes fabric inspection, in-process checks, post-production inspection and a final pre-shipment review before it is packed. Your sweatpants then ship worldwide. The UK is our priority market, and we also deliver to the USA, Canada, Australia and Europe.
